Edvard Munch's Face-Melting Attack of the Tragdorg Armada

Okay, so it’s really just called The Scream, and was painted in 1893. That doesn’t make it any less disturbing though. Here’s how Munch described what inspired it:

I was walking along a path with two friends — the sun was setting — suddenly the sky turned blood red — I paused, feeling exhausted, and leaned on the fence — there was blood and tongues of fire above the blue-black fjord and the city — my friends walked on, and I stood there trembling with anxiety — and I sensed an infinite scream passing through nature.
